Abstract
Objective
This study aimed to measure and compare cerebrospinal fluid neuronal injury biomarkers in the acute phase of complex febrile seizure (CFS) and infection-triggered acute encephalopathy (AE). Furthermore, we determined the pathogenesis of AE with biphasic seizures and late reduced diffusion (AESD).
Methods
Pediatric patients with febrile status epilepticus who visited Hyogo Prefectural Kobe Children's Hospital from November 1, 2016, to December 31, 2022, and whose cerebrospinal fluid samples were collected within 24 h of neurological symptom onset were included. Patients were classified as having CFS or infection-triggered AE according to their definitions. Patients with AE were further categorized into AESD or unclassified AE. Cerebrospinal fluid biomarkers (neuron-specific enolase, growth differentiation factor 15 [GDF-15], S100 calcium-binding protein B [S100B], glial fibrillary acidic protein, and tau protein were measured and compared among the groups.
Results
Total of 63 patients (45 with CFS and 18 with AE) were included. Among the AE patients, nine were classified as having AESD and nine as having unclassified AE. S100B levels were significantly higher in patients with AESD than in patients with CFS (485 pg/ml vs. 175.3 pg/ml) and were even higher in patients with AESD and neurological sequelae (702.4 pg/ml). GDF-15 levels were significantly elevated in patients with AE compared to patients with CFS (85.8 pg/ml vs. 23.6 pg/ml).
Conclusions
The elevation of S100B suggests that activated astrocytes may be closely associated with the early pathology of AESD. Elevated GDF-15 levels in infection-triggered AE suggest the activation of defense mechanisms caused by stronger neurological injury.
期刊介绍:
The Journal of the Neurological Sciences provides a medium for the prompt publication of original articles in neurology and neuroscience from around the world. JNS places special emphasis on articles that: 1) provide guidance to clinicians around the world (Best Practices, Global Neurology); 2) report cutting-edge science related to neurology (Basic and Translational Sciences); 3) educate readers about relevant and practical clinical outcomes in neurology (Outcomes Research); and 4) summarize or editorialize the current state of the literature (Reviews, Commentaries, and Editorials).
JNS accepts most types of manuscripts for consideration including original research papers, short communications, reviews, book reviews, letters to the Editor, opinions and editorials. Topics considered will be from neurology-related fields that are of interest to practicing physicians around the world. Examples include neuromuscular diseases, demyelination, atrophies, dementia, neoplasms, infections, epilepsies, disturbances of consciousness, stroke and cerebral circulation, growth and development, plasticity and intermediary metabolism.
